AiW L-PEDAL.

Application filed. May 27, 1

and LEONARD donxs'ron citizens of the United States, residing at Detroit, county of Wayne, State of lslichigan, haveinvented a certain new and usei.ul Improvement in Anvil-Pedals, and declare the following to be a full, clear, and exact description of the same, such as, will enable others skilled in the art to which it pertains to make and use the same reference being had to the accompanying drawings, which form a part oi this specification.

This invention relates to a combined pedal and latch for swinging out of operative position a winging anvil support 01' spindle.

In the drawings,-Figure l, is a side elevation of the anvil and anvil spindle showing the base which supports the anvil in section, the section being taken on the line A-A of Fig. 8. Fig. 2, is a vertical section taken on the line 'B-B of Fig. 1. Fig. 3, is a top or plan view of the pedal, the base that supports the anvil spindle and the locking device. Fi at, is a verticalsection through the spindle bearing. Fig. 5, is a perspective of the combined pedal and latch release.

a designates an anvil which is intended to be used primarily to supporta fiber shipping case which is" undergoing wire stitching or fastening by wire fasteners.

6 represents the spindle which supports the anvil. This spindle tits into a sleeve or bearing 0 which is provided with a trans versely disposed tubular end (.1 through which engages the pin e that journals the bearing to the brackets f that depend from the base g. The base 9 is the conventional form of casting used as the base of a ma- ,chine and is'not solid but hollow inside to accommodate some of the operating parts of the machine. Surmounted on this base and about the bearing 0 is removable housing h. This housing it contains the spring j which normally presses the latch is into the recess in which the spindle bearing 0 swings.

When the spindle bearing has been thrown back against the adjusting screw Z, the shoulder or hook at on the end of the latch is engages with the forward face of the bear ing 0 and holds the anvil spindle I) firmly in place. It is necessary that this anvil spindle be held firmly in a given position so as to Specification of Letters Patent.

insure the anvil being in correct position under the operating parts of the metal fastener driving machine. 3y turning the adjusting screw Z the exact position of the anvil with respect to the operating parts of the machine ran be fixed. The latch is initially set in correct position so that it will not require subsequent adjustment. If for any reason it should get slightly loose the adjusting sci-cw Z may be turned slightly to insure the tight gripping of the hook on the latch when the hearing has swung back into place.

The forward face oi the bearing a has a slot T-shaped in cross-section. This slot is designated a and is adapted to receive the T bar end 0 of the pedal 7). This T bar end can be dropped into the T slot from the top and will rest against the pin Q at the bottom. This affords a removable connection between the spindle bearing 0 and the pedal so that the pedal together with the latch release may be easily disengaged so as to allow the spindle b to be swung clear down after the spring 9 has been taken off of the hook s. This is desirable because it may be desired to use the operating head of the wire stitching machine for other purposes and the anvil shown in the drawings will not be required.

Pivoted to the pedal 79 is a latch rele in the form of a slightly bent bar t wfhich has an. up-turned and obliquely cut and u. The oblique edge of this end engages with the hook on the latch, as shown in Fig. 8, thelatch being over the oblique edge so as to tip the free end of the latch release slightly above the free end of the pedal p as shown in Fi 5. Consequently when one steps on the free ends of the two pedals, the foot first depresses the pedal 25 to a position of parallelism with the pedal p. This forces the obliquely cut end of the pedal t upward causing the latch to go to the side as shown in the dotted lines oiFig. 3. This takes the case upon the anvil ms: y be changed or the case may be removed {and another case iiisorted over the anvil.

The anvil may be t j irust back to its oper maybe used to pull it back automatically. Immediately that it has passed the hooked end of the latch the spritecauses the hook or shoulderm of the latch to again engage the forward side of the bar 6 and hold the anvil spindle firmly in position.

From the above description it will be seen that by a single operation of the foot both the latch is released and the anvil. tipped toward the operator. Also by reason oi tee arrangement of the pedal and the latch release together they may easily be detached from the pedal so as to allow the pedal to fall coi'npletely forward and out of the way when the machine is desired for other purposes.

lVhat we claim is:

1. The combination of a swinging anvil spindle, a'base for pivoting the same, astop to limit the swing of the anvil spindle in one direction, a spring-actuated latch for engaging the anvil spindle on the opposite side of: the stop to holdit in position, and a comloined pedal and latch release adapted to retact the latch from engagement with the spindle and pull the anvil spindle toward the operator.

2. The combination of an anvil spindle, a base to which the anvil spindle is pivoted, a stop to limit the swing of the anvil spindle in one direction, a springnctnated latch for engaging the anvil spindle on the side oppo site the stop to hold the spindle in a given position, a pedal attached to the anvil spindle for swinging the anvilspindle forward wheii the latch is released, and a latch release comprising, a bar pivoted to the pedal and having an obliquely cut end which engages with the latclnthe said obliquely cut end being ordinarily on the latch so as to force the free end of the latch release above the free end oi? the pedal.

8. The combination of an anvil spindle, a base to which the same is pivoted, a stop to limit the swing of the anvil in one direction, a spring-actnatcd latch for engaging the side of the anvil spindle opposite the stop, a portion of the annil spindle being provided with a vertical slot T-shaped in crosssection andihaving a stop at the lower end of the slot, a pedal. provided with a T-bar end for fitting into the T-shaped slot, and a latch release pivoted to the pedal and provided with an obliquely cut rip-turned end adapted to engage with and to be normally pressed by the latch so that the free end of the latch release is held above the free end of the pedal,

In testimony whereof, we sign this speci- .-ication in the presence of two witnesses.
